Review on Schumacher DSR108 450A Batteryless Starter by Dee Parson

If you're looking for a launcher that works when you need it, this is the one for you! Although they all worked well, after about a year they no longer hold a charge and the battery needs to be replaced. constant charge when not in use. This is really a simple solution. I used the DSR109 on a Subaru Outback that had the inverter on overnight. It charged in about 4 minutes and the car started without hesitation. I also used the DSR109 on my Ford F250 (Diesel 6.0) as a demo - I loaded the DSR109 on another car and disconnected the batteries from the F250, connected the DSR109 and was able to successfully start the pickup. The manufacturer rates the DSR109 at 10 years and over 10,000 cycles, but assuming the supercapacitors are fired several times a day - something we don't do when we start our cars. Considering the cost of replacing batteries in my other jump. Firstly, the price of the DSR109 is more than justified even if it only lasts 3-5 years. I would recommend this to anyone who wants confidence that they will get where they want to go!
